Question Winca S310+ (UIS7862) Android 10 hardware and firmware support, Q&A

[droidmanuser]

Hi guys, I'm urgently looking for support for the Winca S310+ on FYT platform (UIS7862). Maybe someone can help with the following information or has similar problems.
I will work on the S310 issues over time and post updates as appropriate. Perhaps one or the other contribution will prove to be helpful. In this case, please leave me a thank you that motivates me to keep going. Of course you can also help each other.

And by the way: Sharing firmware and MCU is expressly desired.

1. Are there custom firmware for these devices (custom ROMs)? The OEM settings are kept very short and concise.
2. Is it possible to get the MCU of these devices as a backup (and also newer versions)?
3. Are there technical data sheets for the wiring harness? I am looking in vain for an AMP cable for the amplifier. Also, I can't understand why an external Bluetooth antenna is needed and only one 4G antenna can be connected (the sp9853i had 2)
4. The inserted Vodafone SIM card does not go into operating mode. The reception bars appear, but they are blank. The PIN query of the SIM card does not appear and cannot be deactivated.
5. There is a loud bang in the speakers each time I start and exit the radio app. I've observed the same thing when streaming via Bluetooth when changing tracks. The bang is so loud that it scares you while driving and it does not depend on the volume set. I made a short video of it where it can be heard very clearly several times. Maybe someone has an idea what could be the cause?

6. The Canbus does not work reliably. Sometimes the radio stays on and continues playing music after the ignition is turned off and the car is locked.
7. I can't sign in to my google account. The login window for entering the e-mail address appears, but immediately afterwards the application always closes unexpectedly. App updates have been done as much as possible.

Attached is information about my system.

UPDATE:
The last issue #7 was fixed by a firmware update, which I received from Winca.

The inserted Vodafone SIM card does not go into operating mode. The reception bars appear, but they are blank. The PIN query of the SIM card does not appear and cannot be deactivated.

UPDATE:
This issue has also been partially "fixed". Unfortunately, there is still no SIM PIN request from blocked SIM cards. The SIM PIN must first be deactivated in another smartphone. Then this also works in the S310 with mobile data.

CAUTION, PLEASE NOTE!
The unlocked SIM (currently no PIN) can be redefined in the S310, but after the next reboot, as mentioned, no PIN query appears and the mobile data etc. do not work! For some reason, this setting cannot be undone in the S310; the SIM PIN must be deactivated in another smartphone for this purpose!

The SIM PIN request is said to work on systems with an active lock screen (screen lock), but I haven't tested that yet. However, on my old system (sp9853i) the PIN request worked even without an active lock screen.
